ABSTRACT

Objective To evaluate the role of CT imaging in staging of hypopharyngeal and laryngeal carcinoma.Methods 85 patients with hypopharyngeal or laryngeal carcinoma proved by operation were examined contrast-enhanced CT scan.The CT images were analysed by two experienced radiologists who were unknown pathologic results,in combination with the clinical data,the TNM staging of tumors were evaluated,then the results were compared with that of pathology,and Wilcoxon rank sum test was used for statistical analysis.P value less than 0.05 was considered statistically significant.Results The accuracy of the staging of lesions was 70.1% based on clinical data alone,while the clinical informations in combination with CT,the accuracy reached 87.1%,that was of significant statistically(P=0.001).Conclusion CT imaging is useful in staging of hypopharyngeal and laryngeal carcinoma,especially when it is combined with clinical data.
